IMPROVEMENT iN accusa-CHAIRS.

We, CHARLES H. HUDSON and JOEL Bowman, both of the city, county, and State of New York, have invented. a certain new and useful Selfpropelling Rocking Device, of which the following is aspeeification.

I Nature and Objects of the Invention.

.the action of rocking, substantially as hereinafter set forth.

Description ofthe Drawing. Figure l is a side elevation ot' a pair of rockers with our invention applied thereto.

Figure 2 is a top view of the same.. Figure 3 is a detached side elevation of one of the pawls on an enlarged scale. v

Figure 4 is a bottom view of the same.

Figure 5 is a side elevation of a pawl of a different form.

Figure 6is still another modification of the pawl, shown in side elevation.

Figure 7 shows the application of our invention to an ice-chair or vehicle.

Figure S shows the bott-om of the pawl shown in fig. 7.

Gen eral Description.

A A are the lockers, of the ordinary form, held together and secured in place by the rods or bars B B and the shaft O.

Upon the shaft C the dogs or pawls D D are hung,

so as to turn freely about the said shaft.

Stops a c and b b upon the shaft, and the dogs or pawls, prevent the latter from being'thrown too far forward.

rEhe collars or shoulders c c on the shaft serve to keep Vthe pawls from sliding lengthwise of the shaft C.

The bottom surfaces of the pawls, which rest on the carpet or floor, are `provided with cork or rubber pads, i, secured to them by being partlyinserted in holes which are somewhat larger at the inner end than at the outer, whereby the pads are finally held in place i These pads are designed to give the pawl a better liold'upon the floor, and also to prevent their injuring` the carpet or other floor-covering on which they are placed.

Instead of the pads, complete soles of rubber or other suitable materialV may be employed.

The vpawls may be attached at the front, ask

shown, or at the rear endl-ot' the rockers, as maybe stantially as specified.

One 13a-,wl alone may also be applied to veither end,4 near the middle ofthe shaft to which it is hung.

When it is desired to ,turn the rockers to the right or left one of the pawls may be lifted and the other left in operation, which will produce the desired effect.

By inclining the 'body of the rider toward the side to which it is desiietl'to turn, the turning will be fa cilitated.

The pawls may he lifted for thepurpose of turning by cords or chains d (Z attached to them and held by the rider.

In the pawls shown in iigs. 5 and (i the foot is made separate from the stem, and pivoted to it, as'

shown.

In one case a pin, e, and. in the other a projecting corner, f, strikes the shoe, and prevents it turning too far over.

XVhen it is desired to use the rockers on ice, they are made with the bottoms or lower edges in forni like the tread of skates, or merelyin form of an' angle or corner, which is presented to Ythe ice, and gives suicient hold wherebytoguidethe chair, horse, or vehicle. i

rlhe pawl is furnished with sharp projecting spurs or points g (shown in figs. 7 and 8,) which take hold in the ice and urge the chair forward, when a rocking motion is imparted to it. y

Instead of the inserted points g, the pawl may be niade with an edge similar to a saw, the teetl'i of' which 'will act instead of the points g. i n

XVhen the rockers are to be used on. any surface other than ice theyure furnished with rollers or little wheels h. h 71, on which they run, whereby the friction is lessened and the progress of lthe rockers or the chairs or horse mounted thereon rendered easy.

It is obvious that many modifications. may be made in the details of construction of this invention, with: out-departing from its substance, the above descrip-` tion setting forth but a few of such modifications. We do not, therefore, contiue ourselves to the exact form and construction shown and described.

Claims.

-1. The combination with the rockerof a chair, hob- 'by-horse, or other article mounted ou rockers, of the pawl or pawls, substantially as hereinabove set forth.

2. The combination, with the rockers A A, and pawls D D, of the cords or chains fl d, as and for the purpose set forth.

3. The combination, with the pawls D, of thepadsi, substantially as described.

4f The combination, witlrthe rockers A, figs. 7 and 8, of the pawls D, armed with projecting points g, sub- GHAS. H. HUDSON. e JOEL BOWKER. Witnesses: I
